有些牙齿掉光的高龄老人认为既然自己没有牙齿,也就没有刷牙的必要了,其实这种想法是不正确的。刷牙不只关系到口腔卫生,还对保证其他系统的健康具有重要意义。正常人的口腔中通常藏有数以亿计的细菌,老人因为没有牙齿,咀嚼能力相对下降,口腔各种腺体的分泌功能也会下降,就更应注重口腔卫生。一般来说,漱一次口可使细菌减少15%-25%,而刷一次牙则可使细菌减少70%左右,这对于消除老人口中出现异味或口苦,都能起到一定的作用。更为重要的是,很多人并不了解刷牙还可以预防老年肺炎。老年人的吞咽反射功能有所下降,口腔中的异物容易被错吸入呼吸道,引起吸入性肺炎。刷牙时,牙刷会刺激牙龈和牙 Some elderly people who fall out of their teeth think that since they have no teeth, there is no need to brush their teeth. In fact, this idea is not correct. Brushing is not only about oral hygiene, but also important to ensure the health of other systems. Normal mouth usually contains hundreds of millions of bacteria in the mouth, the elderly because there is no teeth, chewing ability decreased, the secretion of various oral glands will decline, we should pay more attention to oral hygiene. In general, rinsing a mouth can reduce bacteria by 15% -25%, while brushing a tooth can reduce bacteria by about 70%, which can play a certain role in eliminating odor or mouth pain in the old population. More importantly, many people do not understand brushing can also prevent pneumonia in older people. The elderly swallowing reflexes have declined, foreign body in the mouth easily be mistakenly inhaled into the respiratory tract, causing aspiration pneumonia.
